i dont remember much about this manga, as i read it many years ago. But from what i remember the seme was really big, and strong. When the uke took him to a bar to meet his friends they all commented on how strong he looks.
i remember the uke had to order sex items online, and there was a scene of him receiving the box.

i know thats not much, but its been a long time.

First thing that came to my mind when I read your description was U Don't Know Me by Na Yeri. The uke definitely received a box of adult items he ordered and he was caught redhanded by the seme (They weren't seme and uke before this happening though haha). Seme is also buff and into sports. Hope you find this 😁

Yes, thats it! Thank you! I've been trying to find it for awhile. =)
